As Gustav requested, I've made a thread dedicated to the installation process, as well as post updates along the way of the G-Power Stage 1 supercharger kit my shop is installing. I believe this is the first G-Power M5 kit installed solely by a shop, without a G-Power technician present during the installation. There is a lot of buzz surrounding the G-Power kits for E60 M5, and we're going to do our best to answer questions and provide insight on the overall kit, from beginning to end.

Member "MuchMoore" has been periodically stopping by our shop, and taking some pictures of his own(posted here: G-Power SK I Install Pics), so do be aware, the progress will likely almost always be further along than what's listed here. This will be the "official" thread for this build.

The subject car is a 2008 M5, sapphire black on full black leather:

A few months prior to the install, we installed an Active Autowerke Exhaust system, along with RD-Sport catless headers as well as a performance tune from AA.

One last "before" shot for the heck of it. . .this is going to look very different when the build is complete.

The first order of business was a basic tear down. This included removal of the OEM airboxes, intake manifold, bumper, fuel rails. Here is a couple pictures showing it in progress.

Once the basic things had been removed from the car, the ECU was pulled out and packaged in a static resistant bag to be shipped to G-Power for tuning.

Stay tuned for more coming soon!

We purposely got the car in 2 days prior to the kit arriving. We figured this would minimize downtime for the customer in the end, as we could get right to business when the kit arrived. Like clockwork, on the 2nd day of the car being at the shop, the kit arrived. Here are pictures of SOME of what's included with SK-I. This was the "special price" so it did not come with the exhaust system, as SK-I usually would from what I understand. Not like we needed it anyway, so all is good.

nice touch on the plaque:

biggest s/c pullies i've ever seen:

plain weave carbon fiber airboxes and plate:

front mount radiator for charge cooling system:

intake manifold stuff, mocked up with water reservoir in the middle:

I have to say, hats off to G-Power in the overall quality of the parts in this kit. The craftsmanship is absolutely unreal. . .everything is either CNC machined or custom sand casted. . .the quality is head and shoulders above most anything on the market today, period. We wasted no time seeing how pieces fit together and worked with one another. . .more updates coming soon!
